METHOD OF EMPTYING A POWDER OR LIKE MATERIAL OUT OF A CONTAINER

摘要

The powder (9) is conveyed out of the container (1) from its free upper surface by means of a stream of carrier air in a carrier-air pipe (6; 10; 12) provided with openings for the powder. The emptying is facilitated by means of a stream of secondary air from a secondary-air pipe (7; 11; 13). The container is rotated so that the fixed carrier-air pipe may come into the vicinity of the surface of the powder.
